' Be it known thatyI, Josnrn A. Jnrrnnx, a citizen of the United States;residingat Duluth, in the county of stnLouis iand State of Minnesota,have invented certain new and useful Improvements "in Loading Devicesfor ldaryesting lvlachinesf of which -the following is a specification,reference being had thereinto theaccompanying drawiiig. 1

side wall 6", which is also a continuation of the opposite side of theconveyer but having depending portion 7 the lowermost edge 8 of whichisi normally parallel with the deck of the vehicle being loaded. Thisdepending portion acts as a shield and guide for the stalks as they arebeing adjusted preparatory to being: discharged from the conveyer to thevehicle. The extension also comprises a rockable shaft 9journale'd, asat 1'2 and 13, within suitable brackets '10 and 11 rigidly fixed to oneside of the conveyer, said shaft being parallel with the side of theconveyer and spaced some little? distance below same.

The bracket lOhasan extension ldupon it the upper portionthereof, inwhich is piv-' otally mounted, as at 15, the bell crank trip ping lever16 comprising the outwardly arched depending portion 17' and the arm 18at substantially right angles thereto. ;The

bracket 10 has formed at right angles thereto the lateral extension 19having a slotted extension 20- formed integral therewith and parallelwith the uppermost attachingportion of the bracket. Into this slottedportion 20 thefree end oftheportion 17of the bell crank 16 extends andis there guided duringits reciprocal travel. I i

Upon theshaft 9 and adjacent the bearing 12 is fiXed a hub 21 carrying.an outwardly extending rod 22 to which is attached a counterweight23,the oflice of which will be dscribedlater. The rod 22' is designed tonormallyrst upon the upper face ofthe ex tension 20 intermediateofthefree endof the portion 17 of the lever 16 and tension 9 0f the bracket10; i

.As a locking means for said rod in the position:=clescribecl a pendulumcatch 24 is pivtlie ex otally carried, as at25, upon the extension l'lofthe lever 16 and has one corner 26, which normally overlaps the rod 22and locks same rigidly in the'lpositionshown. The catch "24 is providedwith a rightan gularly extendinglipim which engages one 7 considered, atripping dog 30 which consists of an upwardly inclined member forliitingengagement with the pin 28. When one of these dogs passes under the pin28 the arm 18 of the lever 16 will be raised, which will V withdraw theextension '17 of said lever from looking engagement with the" rod 22 andallow same to be freely raised at such time] i r i Assuming, now, that abundle of stalks has been elevated .by the lifting slat, 3 and forcedlongitudinally upon the dumping apron 31 the weight thereof willcounteract that of the counter weight 23 and oscillate the shaft. 9 to apoint ,of dumping of the lock the lever while waiting for the per- Iformance of the next trick.

' hen the rod 22 is in'the act of resuming its normal position it willengage themclined surface of the'pendulum catch 24 and operate same tocause it to automatically I prefer to incline downwardly theinner end ofthe apron ,31, as at 33, just beneathj' which is located a downwardlyand in 'wardly curved fixed apron 34, the lower dischargingedge. ofwhich is parallel withthe lower edge 8 of the side wall 6 andsubstantially in a vertical line therewith.

Spaced, a di 'tance beyond the end of this fixed apron 34: isa similarlybent rod' 35 for.

engagementwith the top end of the bundles of stalks for guiding same intheir down with an inclined butting board 36 to prevent the stalks fromsliding. endwise toward the lower. end of the 'conveyer,andtolinsure auniform longitudinal prostration ofthe bundles as they are apron 34.

By this means the bundles,when dumped from the apron 31 on to the apron34 and rod 35, are brought to a fully prostrated horizontal position anddischarged upon the deck of the receivingvehiclein uniform and evensuccession, thus requiringthe minimum of attention during the entireloading of the vehicle and effectually overcomes one of eyond itslocking position, I

Having thus described my invention what I I claim as newgan d desire toreceive by Let.

ters Patent is,

1. The combination, with an inclined corn harvester conveyer trough,having an end less belt conveyer therem, of an extension of the troughbeyondthe discharge endof stalks,'when delivered from the belt, are,held in a position parallel longitudinally, with the I the conveyor belthaving means whereby the trough ,until a predetermined point in'the 1cycle of the belt is reached,when the stalks thus held are delivered ina horizontal positionto an attending vehicle, and means for causing thestalksto assume such horizontal position V- prior to being delivered tothe vehicle.

2, In combination, an inclined corn harvester conveyer trough, having anendless trough beyond'thewdischarging end, of the belt, a tippingapronwithin the extension and parallel with theftrough'and a fixed Iapron, below the tipping apron for 'alini'ng the stalks. horizontallywhile being discharged, substantially as described. L

3. In combination, an inclined corn. harvesterjconveyer trough, anendless conveyer I I belt operative within the trough, brackets fixed tothe discharge end of, the trough, a

shaft journaled within the brackets, an

apron fixed to the shaft a' counterweight fixed to the shaft and opposedto the apron, shaft locking means pivotally carried upon the trough forholding theapron recep tive position, meanscarried by the endless beltfor unlocking the locking, means, and

a second apron fixed toithe trough and dis P posed below the firstmentioned apron, said last mentioned apron having its; dischargeedgeldisposed in a horizontal plane, substantially. as and for thepurpose vdescribed.

,4. A deviceiof' the character described comprising, in combination, atrough having an endless conveyor belt therein, gan extens1on of thetrough beyond the discharge end of the belt, a rockable shaft journaledupon the trough and adjacent the discharge endof theQbelt andsubstantially parallel therew th, an apron rigidly fixed to. the shaft,means operated by the'beltrforhold-- ing or releasing theshaft, and afixed inq i clined apron below the firstmentionedfapron hav ng itsdlscharge edge'substantially hori zontal, asand forthepurposedescribed;

y 5..A device of the character described 7 comprising, in combinatiomatrough'having an endless conveyor belt therein, a receiving apronextending beyond the discharge iend 90 conveyor belt therein, anextension upon-said of the eonveyer belt and parallel With the trough,means whereby the apron is automatically dumped, a fixed apron carriedby the trough and designed to receive the stalks as they are dumped fromthe first mentioned apron whereby, When the stalks are discharged fromthe last mentioned apron, they are fully prostrated.
